The UK has confirmed plans for an app that will warn users if they have recently been in close proximity to someone suspected to have been infected by the coronavirus. The Â鶹ԼÅÄ’s Rory Cellan-Jones explains how the app might work and what concerns there are about its use.

Also in the programme, we take a look at how logistics is faring under coronavirus disruption. In the new world of Covid-19, lockdowns and volatile spikes in demand, how does the industry everyone relies on to make sure the lights stay on, the water keeps running and the supermarket shelves are full, adapt to such a rapid change? We explore how supermarkets, hoteliers, travel agencies, and even Norwegian salmon farms are evolving – and how many have already upended years of business practices in just a few short weeks.

And the independent economist Michael Hughes weighs in on the different approaches the EU and US are taking in keeping people and companies afloat.
